Webt-SNE uses the t-distribution in the projected space. In contrast to the Gaussian distribution used by regular SNE, this means most points will repel each other, because they have 0 affinity in the input domain (Gaussian gets zero quickly), but >0 affinity in the output domain. Sometimes (as in MNIST) this makes nicer visualization.
